ngramtransfer — transfer n-grams from model to model

Synopsis

ngramtransfer [Options] in1.fst in2.fst [out.fst] ngramtransfer [Options] --ofile=out.fst in1.fst in2.fst [in3.fst ...]

Description

Transfers n-grams from a source model(s) to a destination model.

Options

Boolean options accept either true or false as a value, or the default value if neither value is specified.

--backoff_label=INT64
Backoff label. Default: 0.
--complete[=BOOLEAN]
Complete partial models. Default: false.
--context_pattern1=STRING
Context pattern for first FST. Default: no pattern.
--context_pattern2=STRING
Context pattern for second FST. Default: no pattern.
--contexts=FILENAME
Context patterns file for all FSTs. Default: no context patterns file.
--end_symbol=STRING
Class label for sentence end. Default: "</s>".
--fst_align[=BOOLEAN]
Write FST data aligned where appropriate. Default: false.
--fst_compat_symbols[=BOOLEAN]
Require symbol tables to match when appropriate. Default: true.
--fst_default_cache_gc[=BOOLEAN]
Enable garbage collection of cache. Default: true.
--fst_default_cache_gc_limit=INT64
Set the cache byte size that triggers garbage collection. Default: 1048576.
--fst_error_fatal[=BOOLEAN]
If true, FST errors are fatal. Otherwise, returned objects are flagged as bad. For example, FSTs are returned with the kError property set to true, and FST weights set so that Member() returns false. Default: true.
--fst_field_separator=STRING
Set the characters used as a separator between printed fields. Default: " ".
--fst_read_mode=STRING
Default file reading mode for mappable files, "read" to use read(2) or "map" to use mmap(2). Default: "read".
--fst_verify_properties[=BOOLEAN]
Verify fst properties queried by TestProperties. Default: false.
--fst_weight_parentheses=STRING
Set the characters enclosing the first weight of a printed composite weight (e.g., pair weight, tuple weight, and derived classes) to ensure proper I/O of nested composite weights. Must have size 0 (none) or 2 (open and close parenthesis). Default: no parentheses.
--fst_weight_separator=CHARACTER
Set the character separator between printed composite weights. Default: comma.
--help[=BOOLEAN]
Show usage information. Default: false.
--helpshort[=BOOLEAN]
Show brief usage information. Default: false.
--index=INT32
Specifies one FST as the destination (source). Default: not specified.
--method=STRING
Set the transfer method, one of "count_transfer" or "histogram_transfer". Default: "count_transfer".
--ngram_error_fatal[=BOOLEAN]
If true, NGram errors are fatal. Otherwise, returned objects are flagged as bad; i.e., NGramModel::Error() returns true. Default: true.
--normalize[=BOOLEAN]
Recompute backoff weights after transfer. Default: false.
--ofile=FILENAME
Output file (prefix).
--save_relabel_ipairs=FILENAME
Save input relabel pairs to file. Default: do not save.
--save_relabel_opairs=FILENAME
Save output relabel pairs to file. Default: do not save.
--start_symbol=STRING
Class label for sentence start. Default: "<s>".
--tmpdir=PATHNAME
Set the temporary directory to use. Default: /tmp.
--transfer_from[=BOOLEAN]
Transfer from (to) other FSTS to indexed FST.
--v[=INT32]
Set the verbosity level. Default: 0.
